    摘要: The invention concerns a method for making ADN from GUDN in one single process step. GUDN is reacted with an ammonium source (ammonium- sulfamate, ammonium-sulfate) and an ion-change gives ADN from GUDN in one process stage. The advantages are that the process gives pure ADN without potassium contaminants and that a smaller amount of solvent is necessary. GUDN and the ammonium source are heated together with water until everything is solved into a solution. Thereafter, an alcohol is added and the precipitate formed is filtered off. The filtrate is concentrated and the residue is suspended in an alcohol. The precipitate is filtered off and ADN is obtained by concentrating the filtrate. An alternative is to, after adding the alcohol, partially concentrate the then formed mixture. The filtering off of the particles from this mixture yields a solution of ADN in alcohol. Evaporation of this solution yields clean ADN after only one filtering stage. Ammonia can also be used as a source of ammonium. GUDN is then dissolved in ammonia where after then formed ammonium-dinitramide and guanylurea are separated through separation on a column filled with active carbon. The eluted solution is concentrated until dry which yields ADN. GUDN can also be reacted with ammonium-sulfate in alcohol creating a precipitate which is filtered off. The filtrate is concentrated and the remainder is suspended in alcohol. The un-soluted particles are filtered off and ADN is obtained through concentrating
